I hope this message finds you well, present circumstances excluded. I am a licensed attorney with over a decade of employment law experience, with much of that being government sector experience. It is a pleasure to assist you today.
This is a tough situation and it can take one of two courses: (1) Try to stick it out as there are not many legal options here unless you are being discriminated against based on your age, race, gender or because of a handicap - even retaliation suits have to be predicated on those classes of protection under the civil rights act; or (2) try to find another government agency to work for wherein you can transfer your retirement under the state retirement system with your move.
In either scenario, for the time being, it is my recommendation that you document every interaction, both direct and indirect, with this individual. Based on what you have shared with me, I think that discrimination may be at play here, but is not ripe for suit just yet through the EEOC. You need to document and that may later lead to a suit.
I have dealt with this situation many times. I have seen it result in litigation, early retirements and new jobs in different agencies. In my experience, the people that adapt to their new surroundings and kill the afflicting person with kindness are the ones that thrive and ultimately reach their goals, in spite of the obstacles placed in their way.
So, for the time being, I urge you to do just that...take this one day at a time and strive to thrive in the new job. Document your interactions. If litigation is necessary, it will present itself clearly.
Please rate my answer positively and let me know if you have any additional questions or comments.
Thanks and best wishes!
